N = New listing appearing on list for first time
R = Item returning to the list after having been off for 1 or more weeks

Commentary:

* The Wimpy Kid's Cabin Fever slides down again to #26 on the overall list; still #1 here on the comics list. The next several slots are taken up by Kindle editions of Wimpy Kid wanna-bes Dork Diary & Big Nate; makes you wonder how many digital editions The Wimpy Kid could sell if it was available on the Kindle...

* The top debut this week is the non-fiction Health Care Reform. Also debuting are a couple of collections of Marvel's recent event comics and a Star Wars collection.

* Last week's big debut, The Annotated Sandman, surprisingly tumbles out of the top ten all the way down to the bottom of the list.

* Dead Watch: Only four Walking Dead collections on the list this week; I imagine we'll have to wait for the return of the television series in February to see another uptick in Walking Dead sales. (Amazon appears to be out-of-stock on the WD Compendium at present, which is no doubt affecting sales.)

* Tintin Watch: Six Tintin collections this week. I think it's safe to say that the movie has had a positive impact on Tintin comic sales.
